Creating a Robot to Tie a Knot with Lego Mindstorm :: Robotics

Abstract The point of building this robot was to have it successfully complete and tie a knot. The original idea was to have the robot tie knots creating a bracelet. Unfortunately, the process of tying a knot alone was too much work to try and move on to an entire bracelet. I had neither the time nor the insight to build a flexible and usable 'arm.' I tested and modified a design from the Lego Mindstorms book, but found that I could neither open nor close the hand. I continued to further modify the design to be able to grab and let go of string but the result was extremely bulky. Also I could not find a plausible and spaceconstrained way to attach the gears to each of the 'fingers.' The conclusion that I drew was not that the project was impossible but that it needed more time and research. Background The idea for a robot that could neatly and efficiently create a knotted bracelet became a reality after my own experiences of personal pain and triumphs over its creational process. Although the design is merely knotting in a line some people have neither the patience or ability to complete such a simple masterpiece. This is when the idea for a bracelet making robot was first manifested. It is being brought to life for all those who can't or don't want to make one themselves, hence, a robot to do it for them! Unfortunately, two weeks is not enough to make a full blown bracelet making robot. Instead my attempt will be to make a robot that can successfully tie a knot around a string. Which with more time would eventually lead to an entire knotted bracelet. The textile industry has prospered greatly since the age of industry and invention. Cotton, silk, and various other materials are processed and transformed into beautiful fabrics and cloths which soon become clothes and accessories. The flying shuttle was brought to factories in 1733 by the inventor John Kay, improving looms to enable weavers to get their work done even faster. Soon after there came the spinning jenny, and the water frame which became the first powered machine. To be or Knot to be? 3 The inventions kept spewing forth until at last the modern textile machine was born. Most of these are run by computer with nowhere near the machinery. This minimizes injury and ups the efficiency of production. While my robot won't be the next big factory design, it will make a simple but overly complicated knot for a robot. In future years at COSMOS in the robotics cluster, perhaps someone will see my design and continue it, until it completely finishes an entire

Organization for Economic Co-operation and Development Essay

This article has deeply looked into the importances of education. The different perspectives that the author of the article has used in explaining the significance of education has made me to understand the noble part of education which I though was increased economic power. However from the article, I have realized that there are other benefits accrued to education such as improved lifestyle, and also status quo of an individual though they have not been fully exhausted in the article. The completion of tertiary education has also increase in Organization for Economic Co-operation and Development (OECD) members have also learnt that there is inequality in economic earning in the OECD country members with Spain, Luxembourg and Belgium having the lowest level of gender inequality. This however does not conform in all countries especially the developing countries where the level of unemployment is high. There is high level of unemployed graduates in the developing countries which deprive education of its importance. The income rate in the developing countries do not match with education level due to high level of corruption in these countries. It is possible to find a Bachelor degree holder earning less than a college diploma holder. The education in different countries vary in significance and in the developed countries the people enjoy the benefits of education more than the people in the developing countries. The articles analysis on sciences and maths score has brought the clear image of performance across different countries. Just like many people, I could not have imagined that the United States could be led by any other country in the science and technology sector. Amazingly from the articles analysis on these subjects (Science and Maths), Asian countries take a lead including Singapore, China, South Korea and Japan. It have also been noted that different countries differ significantly on the level of education and education attainment. The gender inequality in earning is very prominent in the developing countries which the article should have focused. The article did not include African states in the analysis except in the science and math performance. I feel that the article needed more of comparison on education in Africa with the first world countries which could have brought about a clear view of education in the two disparities. The article could have discussed about the future prospect of education in the world. With the improved technology, different individuals from different countries are able to acquire universal education and hence chances of employment increase. The level of competition in education is also likely to go higher as children at a lower age are being exposed to technology such as the internet. The article need therefore to address the future of education in the globe. The benefits of education are broader than the article is stating. Education plays a major role in the conservation of the environment. The level of education determines the ones level of environmental consciousness. With the threat of global warming, education through creating awareness and providing solutions to the problem can make a difference.
